Remove the hinges and hardware from the cabinets. Lay the doors on a flat surface.
Sand the cabinets and doors with 180-grit sandpaper to remove any existing finish. Wipe the surfaces with tack cloth to remove the dust.
Mark the cabinets and doors with light vertical and horizontal lines using the sharp edge of a key. The lines should be randomly placed and very light. Do not gouge the surface of the cabinets.
Hit the cabinet doors and housing lightly with a chain to create nicks and dents in the surface.
Apply crackling medium to the cabinets with a foam paintbrush. Apply it in a thin, even layer using overlapping strokes that all go in the same direction, such as down the cabinets or across to the left. Let the crackling medium dry. It will produce cracks that add to the distressed look.
Rinse the foam brush. When it is dry, apply a thin layer of interior latex paint on top of the crackling medium in the opposite direction that you applied the crackle. Let the paint dry. Reinstall the hardware and rehang the doors.
